ClearPolyester microfibers delay growth of cherry tomato (Solanum lycopersicum var. cerasiforme) throughout the lifecycle
A lifecycle greenhouse experiment found that polyester microfibers — a common contaminant in soils amended with biosolids — slowed the growth of cherry tomatoes at multiple life stages, and that these effects were caused primarily by the physical properties of the fibers rather than any leached chemicals. Even at a relatively low concentration of 0.5% by soil weight, microfibers measurably impaired plant development. This is significant because polyester microfibers are one of the most prevalent microplastic types in agricultural soils, and their effects on crop productivity could have food security implications.
Effects of microplastics polluted soil on the growth of Solanum lycopersicum L.
This study tested how microplastic-contaminated soil affects tomato plant growth, finding that higher concentrations of plastic particles in soil reduced plant height, root development, and overall crop health. The results suggest that microplastic pollution in farmland could reduce food crop yields and potentially affect the quality of the produce we eat.

Researchers tested the effects of polystyrene, polyethylene, and polypropylene microplastics on tomato plant growth using hydroponic experiments at various concentrations. The study found that all three types of microplastics negatively affected seed germination, root growth, and plant development, with effects varying by plastic type and concentration. These findings suggest that microplastic contamination in agricultural settings could interfere with crop growth and food production.
Effects of polystyrene nanoplastics on tomato plant growth, fruit yield and quality
Researchers investigated how polystyrene nanoplastics affect tomato plant growth and fruit quality, finding that exposure reduced seedling biomass, impaired photosynthesis, and triggered oxidative stress. At higher concentrations, the nanoplastics inhibited mineral uptake and diminished fruit yield along with nutritional quality markers like vitamin C and lycopene. The study highlights that nanoplastic contamination in agricultural soils could pose a meaningful threat to food crop productivity and nutritional value.

Researchers investigated how polyester microfibres, a prevalent type of microplastic in agricultural soils, affect the growth and seed yield of white mustard plants. They found that microfibre contamination altered plant development in ways that could have implications for crop productivity. The study highlights the importance of understanding how microplastic accumulation in farmland may affect the economic yield of food crops.

Sewage sludge containing microplastics was applied to soil and effects on tomato plant growth and fruit development were assessed. Microplastic exposure through sludge-amended soil altered vegetative growth and fruit maturation, suggesting that agricultural sludge application is a route by which microplastics affect food crops.

Researchers investigated the impact of aerial polyethylene microsphere deposition on tomato plants at concentrations of 10, 100, and 1000 mg/L, finding that while shoot biomass was unaffected, exposure significantly altered root metabolite profiles (increasing amino acids, decreasing fatty acids and organic acids) and shifted rhizosphere bacterial and fungal community composition.

A greenhouse experiment found that a 1% w/w mixture of polyethylene, polystyrene, and polypropylene microplastics negatively affected tomato plant development and yield, with statistical analysis confirming significant growth reductions compared to uncontaminated soil.
Can microplastics threaten plant productivity and fruit quality? Insights from Micro-Tom and Micro-PET/PVC
Researchers grew tomato plants in soil containing environmentally realistic levels of PET and PVC microplastics and found mixed effects on plant productivity and fruit quality. While some growth parameters were affected, the microplastics also altered the mineral content of the tomatoes. This study suggests that microplastics in agricultural soil could change the nutritional profile of the food we eat.

Biodegradable microplastics affect tomato (Solanum lycopersicum L.) growth by interfering rhizosphere key phylotypes
Scientists found that biodegradable microplastics, often promoted as eco-friendly alternatives, can negatively affect tomato plant growth by disrupting beneficial soil bacteria around the roots.

Impact of Polystyrene Microplastics on Soil Properties, Microbial Diversity and Solanum lycopersicum L. Growth in Meadow Soils
Researchers tested how polystyrene microplastics of different sizes and concentrations affect tomato plant growth and soil microbes. Surprisingly, some microplastic treatments boosted plant growth and soil nutrients, while others reduced microbial diversity and disrupted soil community networks. The mixed results show that microplastic effects on agriculture are complex and depend on particle size and concentration, making it difficult to predict how contaminated soil will affect food crops.
Presence of High-Density Polyethylene Nanoplastics (HDPE-NPs) in Soil Can Influence the Growth Parameters of Tomato Plants (Solanum lycopersicum L.) at Various Stages of Development
Researchers grew tomato plants in soil spiked with high-density polyethylene nanoplastics at environmentally relevant concentrations, finding that the nanoplastics slowed germination, reduced root and shoot growth, and affected plant physiology at multiple developmental stages. Effects were dose-dependent and more pronounced at higher nanoplastic concentrations. As nanoplastics are now detected in agricultural soils through biosolid application and irrigation, this study raises concerns about the impact of nano-sized plastic contamination on food crop yields.
